Generates documentation from a schema

Note: this is a replacement for MarkdownGenerator

Documents can be generated using either provided Jinja2 templates, or by providing your own

Currently the provided templates are for markdown but this framework allows direct generation to rst, html, etc

This works via jinja2 templates (found in docgen/ folder). By default, only markdown templates are provided. You can either override these, or you can create entirely different templates e.g. for html, latex, etc

The template folder is expected to have files:

  • class.FMT.jinja2

  • enum.FMT.jinja2

  • type.FMT.jinja2

  • slot.FMT.jinja2

  • schema.FMT.jinja2

  • subset.FMT.jinja2

  • index.FMT.jinja2

Most of these accept a jinja2 variable element, except index, schema, which accept schema. See docgen for examples This will generate a single document for every

  • class, enum, type, slot

  • subset

  • imported schema

It will also create an index file

all_class_objects() Iterator[ClassDefinition][source]#

all class objects in schema

Ensures rank is non-null :return: iterator

all_enum_objects() Iterator[EnumDefinition][source]#

all enum objects in schema

Ensures rank is non-null :return: iterator

all_slot_objects() Iterator[SlotDefinition][source]#

all slot objects in schema

Ensures rank is non-null :return: iterator

all_subset_objects() Iterator[SubsetDefinition][source]#

all enum objects in schema

Ensures rank is non-null :return: iterator

all_type_object_names() List[TypeDefinitionName][source]#

static bullet(e: Element, meta_slot: SlotDefinitionName, backquote=False) str[source]#

Render tag-value for an element as a bullet

Limitations: currently hardcoded to be markdown :param e: element that holds the property, e.g. Person :param meta_slot: metamodel property to be shown, e.g. comments :param backquote: if true, render as backquote :return: formatted string

static cardinality(slot: SlotDefinition) str[source]#

Render combination of required, multivalued, recommended, and exact_cardinality as a range, according to Mermaid conventions. Considers ‘required’ and ‘multivalued’ to set defaults for ‘minimum_cardinality’ and ‘maximum_cardinality’.


The different cardinality options are: - 1 Only 1 - 0..1 Zero or One - 1..* One or more - * Many - n n (where n>1) - 0..n zero to n (where n>1) - 1..n one to n (where n>1) :param slot: SlotDefinition :return: cardinality string as used in Mermaid diagrams

class_hierarchy_as_tuples() Iterator[Tuple[int, ClassDefinitionName]][source]#

Generate a hierarchical representation of all classes in the schema

This is represented as a list of tuples (depth: int, cls: ClassDefinitionName), where the order is pre-order depth first traversal

This can then be used to draw a hierarchy within jinja in a number of ways; e.g

  • markdown (by using indentation of “ “ * depth on a list)

  • tables (by placing fake indentation e.g using underscores)

Simply iterate through all tuples, drawing each in the appropriate way

Note: By default all classes are ordered alphabetically


tuples (depth: int, cls: ClassDefinitionName)

class_induced_slots(class_name: ClassDefinitionName) Iterator[SlotDefinition][source]#

Yields all induced slots for a class

Ensures rank is non-null
